I am starting to do my PhD in a few months and I am curious as to what a PhD student actually looks like. It's not like I have never observed how a PhD student live their life as during my master I have been engaged in some research activities where I was required to work with some PhDs as a team. The thing is, I only know how they are doing while in the lab, I never asked personally to them how their life outside university/lab goes on. I read in some online articles, that the stage of PhD for natural science students in general are often depicted as a somewhat chaotic, unordered kind of life. Typically they will take as examples, the lack of free weekends, worsening relationship with girl/boyfriend, little time for travelling, decreasing awareness of self appearance in front of others, and some others. What bothers me is that, those activities are indeed not among my lifestyle to begin with: I don't have girlfriend, I have worked throughout the weekends occasionally during my master, and my mood for travelling very rarely overcomes my desire to read through certain chapter in a textbook (in fact, my biggest entertainment is to watch my favorite series over youtube). So, as for daily activities, I think I can pull through a PhD life. So please mention anything else I should be wary of. I also would like to ask, when you are doing PhD research in a team, what do the other team members expect from you? Will your supervisor put a deadline for certain task given to you? I know that the answer may vary depending on region, but I don't care, I just want to hear as many experiences as possible because the place where I am going to do my PhD is abroad.
